The invention relates to the technical fields of design and manufacture of ships, in particular to an ammonia refrigeration ocean finishing boat. The technical scheme adopted by the invention is as follows: according to the ammonia refrigeration ocean finishing boat for saury and squid, a refrigeration device is an ammonia refrigeration device; and ammonia is used as a refrigeration agent. The ammonia refrigeration ocean finishing boat disclosed by the invention has the benefits of refrigeration, environment friendliness, high unit volume refrigeration amount, high refrigeration efficiency, high energy-efficiency ratio, low price, safety, reliability and long service life of a freezing device. Due to the selection of a special high-quality freezing pipe, the use safety is ensured; due to the adoption of oxygen gas-acetylene welding, the defects of welding slag, welding penetration insufficiency, slag incision, air holes and the like caused by the conventional welding are overcome; the welding quality is ensured; a unit manufacture mode is applied; and according to a manufacturing method for integral hot-dip galvanizing, the phenomenon that a closed welded junction position corrodes in a damp environment is avoided and the service life of the pipeline can be better prolonged.
Description
technical field [0001] The invention relates to the technical field of ship design and manufacture, in particular to an ammonia-refrigerated ocean-going fishing boat. Background technique [0002] At present, many fishing boats manufactured in China do not have special refrigeration equipment, and most of them carry ice cubes for freezing and preservation. Fishing boats need a lot of ice cubes when they go out to sea, which is time-consuming and energy-consuming. The operating time cannot be guaranteed, and the daily workload is small. Although the existing method of ice refrigeration through an ice maker solves the problem of carrying, the freezing efficiency of the ice maker refrigeration is low, which will affect the quality of fish caught. HCFCs (hydrochlorofluorocarbons) are also used in the refrigeration of existing fishing boats. This kind of refrigerant will not only damage the ozone layer of the atmosphere, but also have a greater impact on the global warming effect...
